  4. Transgressing safe boundaries Global fresh- water use … Rockström et al. 2009Nature, 461 (24): 472-475

  5. A new ”global spec” for world food production • Stay within 350 ppm, an agricultural system that goes from being a source to a global sink • Essentially a green revolution on current cropland (expansion from 12 % to 15 %) • Keep global consumptive use of blue water < 4000 km3/yr, we are at 2,600 km3/yr today and rushing fast towards 4000 km3/yr • Reduce to 25 % of current N extraction from atmosphere • Not increase P inflow to oceans • Reduce loss of biodiversity to < 10 E/MSY from current 100-1000 E/MSY

  6. No farming system in the world fulfills the new requirements in the Anthropocene of boosting productivity in a resilient way within planetary boundaries... Photo Mattias Klum Photo Mattias Klum

  7. All evidence indicates that this requires investments in redundancy which collides ”head-on” with conventional success strategy Photo Mattias Klum

  8. Can it be done? Innovations for Integrated systems approaches linking land, water, nutrient, and crop management, within context of shaping new consumption lifestyles. Science led co-design one strategic avenue...
